Unemployment lasting longer for the unemployed

This isn't good:

An unusually large share of workers have been out a job for more than six months even as overall unemployment has remained low, a little-noted weakness in the labor market that analysts said threatens to intensify the impact of the unfolding economic downturn.

In November, nearly 1.4 million people -- almost one in five of those unemployed -- had been jobless for at least 27 weeks, the juncture when unemployment insurance benefits end for most recipients. That is about twice the level of long-term unemployment before the 2001 recession.
